4-127
03- 30 Pulse Input Selection *1
Range
【0】: Common Pulse Input
【1】: PWM (Pulse Width Modulation)
*1: It is new added in inverter software V1.4.
There are two modes in pulse input selection:
03-30=0:
Common Pulse Input
Pulse Input (PI) = the selected frequency divided by pulse input scaling (set by 03-31), corresponding to
the maximum output frequency of motor 1 (01-02).
Note: Monitor parameter 12-79 (pulse input percentage) displays the proportional relationship between
input signal and 03-31 (pulse input scaling).
03-30=1: PWM
(Pulse Width Modulation)
It is required to input the correct frequency.
PWM= posedge pulse time divided by previous pulse time period, corresponding to the maximum output
frequency of motor 1 (01-02).
Note: Monitor parameter 12-79 (pulse input percentage) displays the proportional relationship between
the positive edge of input signal and time period.
Note: Tolerance range of pulse time period in PWM modes is ±12.5%. If it is over than the range, it is
inactive.
